Overview:
- We used data from Schwaighofer et al. (2016) who preregistered their study [here][1]
- Schwaighofer et al. investigated if the worked example effect depends on prior knowledge, WMC, shifting ability, and fluid intelligence (original study published in JEP)
- We analyzed self-explanation data from Schwaighofer et al. and used conditional process analysis to test if the worked example effect is mediated by self-explanation quality, and if any effects are contingent on the moderators prior knowledge, executive functions, and fluid intelligence.
- This study is our original investigation of the SE quality as mediator in the worked examples – problem-solving paradigm.

- Open Access paper (pdf)
- Data set including variables used in this study (except for demographic variables including covariates age and semester)
- Copy of output for all reported analyses
- Syntax (except for conditional process analyses; analyses can be reproduced with information in the output file)
- Study overview, materials and codebook
Notes:
- Results cannot be exactly reproduced with the shared data set because age and semester (covariates) were taken out from the data set to ensure participants' anonymity. A combination of demographic variables could theoretically identify a person. Please reach out to us if there are any concerns and we happily provide any other needed information.
- We also happily share study materials in ppp (editable format)!
